HARVESTER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 309,203, dated December 16,1884.

Application lilcd hlay 1 18%.

To (all whom it may concern.-

Be it known that we, V. H. CLARK and A. O. HANKnvsoN, citizens of the United States, residing at Harper, in the county of Harper and State of Kansas, have invented certain new and useful Improvements in Harvester Attachments; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a longitudinal sectional view. Fig. 2 is a side view.

This invention has relation to pitmairconnections of the sickles of reapers or mowingmachincs; and it consists in the construction and novel arrangement of devices, as hereinal'terset forth, and pointed out in the appended claim.

In the accompanying drawings, the letter A designates the head of the sickle-bar, which may be made of wrought or malleable cast iron. It is formed with the lug B on its upper portion, said lug having welded or cast in a transverse seat made therein the chilled iron or steel plug 0, which is recessed in each side to provide the lateral concave conical bearings D.

E represents the pitman, which is made with a forked end, the branches F F of which are separated sulticiently to embrace between them the lug B. The terminal portions of the branches F are provided each with an in wardly-turned coneshaped bearing-stud, G, adapt- (Xo model.)

I ed to engage a conical bearing, D, of the lug. Through the branches of the fork of the pitholt, K. is passed through said perforations. This bolt is perforated near its point end, and is provided with a nut, L, having face-studs m, adapted to formv stops for a key, S, which,

ciently to bring the cone-points of the fork into proper engagen'ient with the bearings 0f the lug, is passed through the eye in the point of the screw, holding both nut and screw in relative position. the wear or lost motion or" the points in the conical bearings can be readily taken up when necessarvand a loose and rattling joint avoided. A safety-bolt may be passed through the y when deemed advisable.

l Having described this invention, what I claim, and desire to secure by Letters Patent,

lateral steel recess-bearings D, of conical form, of the forked pitman having its branches provided with conical studs to engage the bean ings D, and a takc-up screw, K, having a stud when passed through a perforation in the point of the screw, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
